Я новичок в LXC/LXD и хотел бы начать их использовать, но столкнулся с проблемой при запуске нового образа Ubuntu 22.04.
Я установил lxd с помощью snap, следуя инструкциям, указанным наСтраница установки LXD.
lxc launch ubuntu:22.04 test
lxc shell test

Aug 29 14:34:32 test snapd[7253]: handlers.go:662: Reported install problem for "snapd" as already-reported
Буду признателен за любую помощь в поиске и решении проблемы (и заодно за получение дополнительной информации о LXC/LXD).
решение1
Это не «решение», но мы увидели, что snapd
пакет влияет на это, как указано выше.По какой-то причине, он snapd.seed.service
никогда не заканчивается. apt-get purge snapd
а затем apt-get install snapd
(если он вам нужен/хотите его установить) кажется, что он каким-то образом обходит проблему.
Проблема, по-видимому, связана с этими предварительно загруженными снимками:
snaps:
-
name: core20
channel: stable
file: core20_2015.snap
-
name: snapd
channel: stable
file: snapd_20092.snap
-
name: lxd
channel: 5.0/stable/ubuntu-22.04
file: lxd_24322.snap
Этот список предварительно загруженных снимков, кажется, "вшит" в образ, так сказать. На машине, где образ ubuntu:22.04
работает, это означает, что эти снимки доступны по умолчанию:
root@hip-weasel:~# snap list
Name Version Rev Tracking Publisher Notes
core20 20230801 2015 latest/stable canonical✓ base
lxd 5.0.2-838e1b2 24322 5.0/stable/… canonical✓ -
snapd 2.60.3 20092 latest/stable canonical✓ snapd
Обходной путь
Когда вы делаете apt-get purge snapd
и apt-get install snapd
, эти снимкинетpre-seed больше нет. Вот почему это "работает". Но было бы интересно узнать больше опочемуэто происходит ипочему только на некоторых наших машинах...
